parallel relation with common inlet and outlet passages for said sides.

It is still another object of the invention to provide a radiatorcomprising a vertically disposed narrow chamber formed by spaced platesfolded into zigzag substantially V- shape folds, said radiator havingouter sides diverging at one end and then extended substantiallyparallelinsaid zigzag folds, said radiator having inner sides whichextend reversely to the outer sides and substantially paralleltherewith, said inner sides being connected at their ends and having acommon outlet. I I

These and other objects and advantages of the invention will be fullyset forth in the following description made in connection withthe-accompanying drawings in which like reference characters refer tothe same parts throughout the different views, and in which,

Fig. 1 is a view partly in plan with certain portions broken away, andpartly in horizontal section;

Fig. 2 is a view in side elevation of the radiator with the centralportion broken away;

Fig. 3 is a vertical section on the line 33 of Fig. 1, as indicated bythe arrows and shown on an enlarged scale; and 1 Fig. 4 is a viewsimilar to Fig. 1 showing a modified form of the radiator.

I Referring to the drawings, particularly Figs. 1, 2 and3, a radiator isshown comprising vertically disposed narrow water chambers 5 formed byspaced vertically disposed plates 6, extending toward each other in anected by a suitable posed at each side of and adjacent Serial No.504,185.

somewhat inclined direction from the topand bottom and being connectedtogether. While various forms of connecting means may be used, in theembodiment of the invention illustrated, theplates are shown as weldedtogether (see Fig. 3). Chamber 5 comprises portions 5a which are incommunication at one end of the radiator and have connected theretotheinlet conduit 7 said conduit being shown as connected by a suitablenipple Sand elbows 9 to a steam or hot water supply pipe 10. Theportions 50, diverge at a comparatively wide angle and are then bentinto zigzag folds 56 substantially V-sha'ped in form. The zigzag folds51) extend longitudinally at each side of the radiator andinsubstantially parallel relation. the other end of the radiator, thechambers 5 extend .reversely to form the zigzag folds 50, alsosubstantially V -shaped in form, which extend .in a directionsubstantially parallel to that of the folds 5b and within the latter.The

inner ends offolds 50 are connected at 561 a and an outlet pipe 11connects with this common point of the folds 50, said pipe beingconnipple 12 and elbows 13 1 1. Brackets 15' are dis- 7 each end of theradiator adapted, to rest on the floor or other, supporting surface andsaid brackets have substantially V-shaped portions 15a extending upwarda short distance into the to a discharge pipe .angle between portions 5aand 5b. The

brackets 15 are connected by rods 16 extending therebetween and threadedthereinto at their ends, said rods being equipped with suitable jambnuts 17. At the end of the radiator opposite the pipes 7 and 11, the rod16 passes through triangular blocks 18 extending upward into the anglebetween folds 50, said blocks also being contacted by the jamb nuts sitepipes 7 and 11 is also provided with suitable air relief cocks 20. Itwill be noted that the inlet 7 is substantially at the upper end ofchambers 5 while the outlet pipe 11 is substantially at the bottom ofthe radiator. A cover 21 is provided composed of thin flat metal havinga diamond-shaped latticework" formation and having a flange 21a substan-19. The radiator at the end oppotially rectangular in form adapted tofit around the outside of the radiator and ex tended downward a shortdistance from the top thereof. The width of the various strips 21b ofthe cover are illustrated as somewhat wider than the chambers 56 and 56.

In operation, the heating fluid will enter the radiator from the pipethrough the pipe 7 and will pass through both of the memcrs 5a throughthe folds 5]) and reversely through the folds 50, passing out throughpipes 11 and 14. The outer sides of the radiator formed by the chambersin folds 5?) will be the hottest part and these sides are exposed to theatmosphere of the room to be heated. The cooler part of the radiatorwill be that formed by the folds 5c and the exposure of this part of theradiator is not so ellicient or so important as that of the outer side.By having the adjacent points of folds 5b and 5c alined, a series ofpassages sub stantially diamond-shaped in cross section are formed,which, together with the space between the members 5a and the inner endsof folds 5c, are enclosed by the radiator or the chamber 5. The air canthus pass" upwardly through the radiator and a large proportion ofheating surface is obtained relative to the amount of heating fluidused. A very efiicient radiation is thus obtained. The radiator isparticularly adapted to ltc made from sheet metal. The plates for thevarious portions, such as the outer folds an and the end of members 5aand the inner sides ormed by folds 50, can be made separately. Theplates at each side of the chamber 5 can then be connected at top andbottom, as by welding, and the various sections then connected at theirmeeting ends and" welded, A substantially unitary structure is thusobtained. The folded form of the radiator gives ample opportunity forexpansion and contraction. The structure is thus extremely simple andvery efficient.

In Fig. 4, a somewhat similar radiator is shown having only the twosides. The radiator also comprises the narrow chamber formed by thespaced plates 26 which are arranged in substantially parallel members orsides, each formed in a series of folds 26?) substantially Vshaped inform. The folds 26b, at each side of the radiator, are arranged withtheir adjacent points in trans verse alinement and the two sides areconnected at each end of the radiator, an inlet pipe 27 being providedadjacent the top of the radiator at one end and an outlet pipe 28 beingprovided adjacent the bottom of the radiator at the other end. The'plates 26 will be connected at their tops and bottom in some suitablemanner, as by welding. A top 29 is also provided adapted to correspondto the ends of the radiator and having the parallel side portions 29aprovided with a vertical flange extending downwardly a short distanceand comprising the intersect ing or latticework arms 29?) which aresomewhat wider than the chambers 25.

In operation, the heating fluid will enter the inlet pipe 27 and willpass in both directions to the opposite sides of the radiator to theother end thereof and pass out through the outlet pipe 28'. A veryefficient radiating eliect is obtained as there is a large exposedsurface in proportion to the volume of heating fluid. The two sides ofthe radiator form-an enclosed space composed of substantially closedpassages diamond-shaped incross section, through which the air can passupward. The radiator shown in Fig. 4, like that shown in Fig. l, isespecially clesigned to'be made of plate or sheet material and can thusbe easily and inexpensively produced.

It will, of course, be understood, that vari ous changes may be made inthe form, details, arrangement and proportionsof the parts withoutdeparting from the scope of applicants invention, which, generallystated, consists in a device capable of carrying out the objects aboveset forth, in the novel parts and combinations of parts, disclosed anddefined in the appended claims.

Cross reference is hereby made to my previous application for UnitedStates patent on this same invention, filed January 30, 192?)", SerialNumber 84,961, and entitled Radiator for heating, formally allowedAugust 9, 1928, forfeited for failure to pay the final Governmentfeethereon and not renewed.

l Vhat is claimed is=- 1. A radiator comprising narrow vertical chambersdiverging from a common end portion and then formed into substantiallyV- s'haped zigzag folds and extending in spaced parallel relation toform the outer sides of said radiator, said sections then extendingtoward each other and reversely in V-shaped zigzag folds substantiallyparallel to each other and parallel tofsaid first mentioned folds toform inner sides of said radiator, said inner sides being joined attheir ends, an inlet conduit at said first mentioned common end portionand an outlet conduit at said last mentioned end portion.

2. The structure set forth in claim 1', said chambers having theirportions diverging and spaced from said common end parallel to the endportions of said inner sides which are joined together. v

3. The structure set forth in claim 1 the points of the V-shaped foldsof said chamber at the outer sides of said radiator having their innerpoints adjacent and transversely alined with the adjacent points of saidV- shaped folds of said inner sides.

4. A radiator comprising, narrow vertical chambers joined at one end, aninlet conduit at said end, said chambers diverging from said end, thenextending generally parallel to each other, then extending toward eachother and then extending in general parallel spaced relationship betweenthe first parallel portions in a direction towards said first end, andthen extending toward each other to join each other and an outletconduit leading from said chambers.

In testimony whereof I afilx my signature.
